CoNDulT FOR TRAoTloN-ROPE RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 281,562, dated Julyglf, 1'883.

- Application tied May 1,1883. (No model.) l Y l .To all whom, t may concern Beit known that I, EDWARD SAMUEL, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Oonduits for Traction.-Rope Railways, of which the following is a specification.

My invention consists of certain improve ments, fully described hereinafter, ,in the construction of underground conduits for traction-rope railways.

In the accompanying drawings, Figure l is a transverse vertical section of mylimproved conduit; Fig. 2, a transverse section of the troughwithmodiiied form of support for the same; Fig. 3, a section showing amodification ofthe upper portion of the conduit; and Fig. 4, a perspective View, showing portions of two adjoining sections of the trough.

My improved conduit is composed of the trough'A, made in sections and provided with flanges a c, the detachable and adjustable bars WV W', also made in sections, and the supports secured to the troughat suitable intervals, 'and bearing on appropriate foundations made in the bottom of the Vtrench formed in lthe ground forV the reception of the conduit. The sections of the trough are made of plate-iron or plate-steel, each section being made in one piece bybending or rolling, or both.

Vhile it is not necessary to adhere to the precise shape shown of the trough, I prefer to make it with a rounded base and with opposite parallel sides, b Z), terminating in the 'aforesaid anges a c. The trough thus made of plateiron or plate-steel in sections of suitable length is more economical than a cast-iron trough, inasmuch as it is very much lighter and can be made with facility by' properly-constructed bending and rolling mill appliances. The

trough, however, demands the use of suitable supports, D, at intervals. These may be made of wrought-iron bars, as shown in Fig. l, the bars being welded, riveted, or bolted together and secured to the trough 5 or each support may be made of cast-iron, as shown in Fig. 2 5 or the supports may be composed partly of wrought and partly of cast iron, constructed in any manner which the judgment of those eX- pert in vsuch matters may suggest, for, whileit essential that the plate iron or steel trough should be combined with suitable supports, my invention is not restricted to any specific mode of constructing the latter.

There should be supports at the junctions of the sections, as shown in the perspectiveview, Fig. 4, one support being common to two adjoining, sections, thereby serving to maintain,

also be made for the lateral adjustment of the bars W W on the trough and for the detachability of one or both of the bars, as described in another application which I have filed for a patent. p Each section of each set of bars WV WV has a flange, e, at the top, and a flange, j', at its low- I er edge for attachment to the Iianges of the trough; but this attachmenty should be such as to permit the lateral adjustment of the said bars on the trough.

rIhe bars are so arranged that there shall be a continuous slot, I', between the anges e e, for the admission of the arm, which extends from the car to the traction-rope within the conduit.

While the bars W W may be made of castiron, I ymuch prefer wrought iron or steel rolled to the desired shape.

The plates may be provided with turneddown iianges for receiving setscrews, the points of which bear against the flanges of the trough, as shown in Fig. 3, and described in my said former application for a patent.

I claim as my invention- Atraction-rope conduit in which a series of troughs, A, made of plate iron or steel,` are combined with two sets of bars, W WV, one or both sets being removable, and with supports D, substantially as set forth.

fIn testimony whereof I have signed my name to this speciiication in the presence of two subscribing witnesses. y
